Step down from a bed made to accommodate single guy (8)
I believe the answer is:
abdicate
'step down' is the definition.
(I've seen this in another clue)
'a bed made to accommodate single guy' is the wordplay.
'made' is an anagram indicator.
'to accommodate' indicates putting letters inside.
'single' becomes 'I' (I as in one).
'guy' becomes 'cat' (American slang for man, esp in Jazz).
'bed' is an anagram of 'bde'.
'i'+'cat'='icat'
'bde' enclosing 'icat' is 'bdicate'.
'a'+'bdicate'='ABDICATE'
'from' acts as a link.
(Other definitions for abdicate that I've seen before include "Renounce one's throne" , "Give up a throne" , "Give up power" , "quit" , "Leave throne" .)
